domain of f(x)= 4/(x+1)+5

domain

f (x) = \frac{4}{x + 1} + 5

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

f (x) = 8 x^{2} - x^{4}

f (x) = 72 - x^{2} + x

f (x) = \frac{x - 3 x - 10}{x ^{2} - 16}

- 8 x (1 - x^{2})^{3}

f (x) = (x - 3) (x + 5)

What is the domain of f(x)= 4/(x+1)+5 ?
The domain of f(x)= 4/(x+1)+5 is x<-1\lor x>-1
